Tuesday Tip: Golden Blonde to Red in 30 Minutes

This young lady came to a class I was teaching with 2 inches of new growth that was natural darkest blonde/lightest brown with no gray.
From the photo you can see she was previously lightened to a golden blonde.
I thought she’d look better as a redhead.
So, First I shampooed her with clarifying shampoo and towel dried her hair.
Then I mixed 45g of 6RO + 15g of 4RO and 60g of 10-volume developer.I always clarify before coloring or bleaching the hair.
I applied to the new growth for the first 10 minutes and pulled the color through all the remaining hair for the last 20 minutes.
Total processing time was 30 minutes.
I think she looks much better as a redhead. What do you think?
